9.8. Connecting An Active Antenna
The FMD55 is prepared for the supply of an active antenna
with 12V DC max. and approx. 300mA. This however not
activated on delivery. On the output of the antenna there
would be a constant 12 V and on connecting a balun
transformer, the power would be short circuited.
In order to activate the power supply you must insert the
glass fuse supplied (500 map slow-blow).
For this you must unscrew the four screws on the side, and
remove the half-casing containing the loudspeaker. To do
this, pull out the casing about 5mm and lift carefully. Pull out
the connection for the speaker. Insert the fuse in holder
found next to the antenna connection. Place the half-
casing back in its original position and reconnect the
antenna socket. Now replace the casing under the front
frame as withdrawn so that the screw-holes are exactly
conforming and screw together.
From now on there is a voltage o 12 V on the internal
conductor of the antenna socket.
